UNITED STATES PATENT 1I) Claims.

This invention relates to a valve which may be usedadvantageously inhigh pressure systems.

The principal object of the inventionis the provision of a valve of suchcharacter that the valve member or body may be moved between a closedposition on its seat, and a fully open position clear of or entirelywithdrawn from the flow passage, to reduce resistance and friction to amlnlmllm.

A further object is the provision of a valve having the aforesaidattributes with the additional advantage that the valve member or bodyin its closed position will be balanced in such manner that the pressureof the fluid at the inlet side will assist in effecting the openingmovement of the valve; that during the travel of the valve member orbody to the open and closed position it will be unbalanced in order tooffer the least obstruction, resistance and friction t the iiow of fluidthrough the valve; and that the valve member or body in the fully openposition will oier no obstruction and afford a maximum flow of iuidaccording to the size of the valve.

Other advantages are the valve is easy to operate, gives anuninterrupted fiow, and is otherwise of substantial and efficientdesign.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read inconnection with the accompanying drawings, in which:

Fig. 1 is a vertical longitudinal sectional view of a valve embodyingthe invention, the valve member or body being shown in the closedposition.

Fig. 2 is a View similar to Fig. 1 but showing the valve member or bodyin a partly open position, portions of the valve being broken away.

Fig. 3 is a view similar to Fig. 1 but showing the valve member of bodyin the fully open position, portions of the valve being broken away.

Fig. 4 is a central vertical longitudinal sectional view of the valveshowing a modification, the bonnet being removed and the stem broken oi,the valve member being shown in the closed position in full lines and inthe open position in dotted nes.

Fig. 5 is a view similar to Fig. 4, but showing a further modication.

Referring now more particularly to Figs. 1, 2 and 3, it will be apparentthere is shown a Valve which includes a casing I0 having a flow passageII extending therethrough with an inlet end I2 and an outlet end I3. Thecasing I0 has an extension I4 lproviding a space I5 above the passage Ilin communication therewith. The passage II extends straight through thecasing. A seat I6 is located in the passage II- coaxially thereofbetween the inlet and the outlet but nearer the latter than the former.This seat may be of any suitable form. In the present instance, the seatis replaceable and consists of a ring in threaded engagement with thecasing with an internal veircular surface I'l approximating the passageand-'a conical surface I8. A valve member or body I9 in the form of adisk cooperates with the seat I6 to control the flow of the fluid. Thevalve serves advantageously in steam lines but obviously it may be usedto control the ow of gas or liquid. The disk I9 is beveled to conform toconical surface I8 as well as the circular surface Ilof the seat I 6.

Means 20 is provided which is operable to'cause the movements of thedisk I9 to the closed position on the seat, to the open position intothe space l5 clear of the passage II, and vice versa. Also, to changethe angularity vof the disk during its travel to the open and closedposition'. Said means 20 may be diversely formulated. vAs shown in Figs.1, 2 and 3, said means 20 consists of links 2I, 22, 23 and 24. The link2l Ahas the opposite ends thereof pivotally connected with a fixed pivot25 and the disk I9, respectively.' The pivot 25 is supported by thecasing I0. The connection of the link 2| to the disk I9 is accomplishedbyV a lug 26 and a pivot 2l extending through the link 2| and thelug'26. The lug 26 is on ther` inlet side of the disk and near thecenter thereof. One end of the link 22 is pivotally connected with thepivot 25 and its opposite end is pivotally connected, as at 28, with oneend of the link 23 whose other end is pivotally connected, as at 29,with a lug 30 on the disk at the inlet side thereof and in spacedrelation to the lug 26. The lugs 26 and 30 are at opposite sidesrespectively of the geometrical center of the disk.

One end of the link 24 is pivotally connected, as at 3l, with the link22 between the ends thereof, and the opposite end of the link 22 ispivotally connected, as at'32, with a lug 33 on a coupling 34. Thecoupling 34 swivelly receives fth'elower end of a stem 35 rotatablysupported by suitable glands 36 and packing v3'I carried by a bonnet 38on the casing IIJ. The stem 35is in threaded engagement with a bushing39 'on the top of the bonnet and a hand wheel 40 or any other., suitablemeans serves for actuating the stem'35v to operate the means 20 for thepurposes mentioned.

Upward movement ofthe stem by rotating it counterclockwise causes thedisk I9 to move from the closed to the open position and simultaneouslychanging its angularity to unbalance the disk. With the disk I9 in itsclosed position, as shown in Fig. 1, when the stem 35 is moved upwardly,a pulling force is applied to the disk at a point below the center ofthe disk through the intervention of the links 24, 22 and 23, pivot 29and lug 3B. At the same time, the disk I9 rocks on the pivot 21 out ofits balanced closed position. The upper half of the disk moves away fromthe inlet side under pressure of the fluid while the lower half of thedisk moves toward the inlet side. Thus pressure of the uid `aids ineffecting the opening movement of the disk in conjunction with thepulling force applied by the stem 35 an-d means 20. As the rotation ofthe stem 35 continues, the disk [9 continues to travel toward the openposition guided-hy theelink-ZI vduettoth ef ::co nnectfigon of thelatten with theffixed pivot'ff. `3Meanwhile the disk assumes an angleapproximately paralleling the longitudinal axis of the passage l whenthe disk reaches said axis, as shown in Fig,A4 2.
